Complete each sentence by dragging the proper label into the appropriate position. Then rearrange the sentences so they accurately explain the chronological order of digestive processes. Once sentences are complete, drag & drop the labels below into the correct order. Once foods are broken down into chemical monomers, the digestive system works to mastication move nutrients from the Gl tract into the cells ofthe body via compaction Indigestible residues along with some of the non-reabsorbed secretions of digestive organs, undergo where the fluids are removed and a remaining solid is created. secretion The final step requires defecation where the fecal matter resulting from compaction is excreted from the body. ingestion Starting in the mouth, the mechanical and chemical breakdown of food is referred to as the process of digestion absorption The digestive process begins with the of foods deglutition Reset References Composition Choose add-ons Speed up browsing by disabling add-ons.

Mantle convection  is the slow  creepingmotion of earth's solid silicate  mantle  caused by  convection  currents carrying  heat from the interior  to the planet's surface.[1][2]  the earth's surface  lithosphere, which rides atop the  asthenosphere  (the two components of the  upper mantle), is divided into a number of  plates  that are continuously being created and consumed at their opposite  plate boundaries. accretion occurs as mantle is added to the growing edges of a plate, associated with  seafloor spreading. this hot added material cools down by  conduction  and  convection  of heat. at the consumption edges of the plate, the material has thermally contracted to become dense, and it sinks under its own weight in the process of  subduction  usually at an  ocean trench.[3]this subducted material sinks through the earth's interior. some subducted material appears to reach the lower mantle,[4]  while in other regions, this material is impeded from sinking further, possibly due to a phase transition from  spinel  to  silicate perovskiteand  magnesiowustite, an  endothermic reaction.[5]the subducted oceanic crust triggers  volcanism, although the basic mechanisms are varied. volcanism may occur due to processes that add buoyancy to partially melted mantle causing an upward flow due to a decrease in density of the partial melt.secondary forms of convection that may result in surface volcanism are postulated to occur as a consequence of intraplate extension[6]  and  mantle plumes.[7]it is because the mantle can convect that the  tectonic plates  are able to move around the earth's surface.[8]mantle convection seems to have been much more active during the  hadean  period, resulting in gravitational sorting of heavier molten  iron, and  nickel  elements and  sulphides  in the core, and lighter  silicate minerals  in the  mantle.
